iT3012E
8 GHz Differential-to-Single-Ended Amplifier
Description
The iT3012E is a RoHS-6-compliant packaged differential-to-single-ended amplifier designed
for use as an optical modulator predriver with limiting functionality in 10.7 Gb/s and 12.5 Gb/s
(OC-192) optical transmitters and receivers. It allows single-ended input signals of 350 mVpp to
900 mVpp or differential signals of 250 mVpp to 1800 mVpp to be limited at a constant single-
ended output voltage of 1.9 Vpp. It provides output voltage control and allows external offset
correction. iT3012E also provides excellent linear performance when operating at lower output
voltages. Both AC and DC input coupling are allowed. DC-coupled SCFL differential input
(input “high” voltage = 0 V, input “low” voltage = -900 mV) is allowed.
